Veterinary anaesthesia and analgesia

Randomized Controlled Trial
Evaluation of intravenous administration of alfaxalone, propofol, and ketamine-diazepam for anesthesia in alpacas.
To evaluate the effects of induction of anesthesia with alfaxalone in alpacas. ⋯ All protocols were adequate for induction of anesthesia. Alfaxalone alone in unpremedicated alpacas is not recommended.

Clinical Trial
The use of a nerve stimulation test to confirm sacrococcygeal epidural needle placement in cats.
To determine if a nerve stimulation test (NST) could act as a monitoring technique to confirm sacrococcygeal epidural needle placement in cats. ⋯ This study demonstrates the feasibility of using, in a clinical setting, an electrical stimulation test as an objective and in real-time method to confirm sacrococcygeal epidural needle placement in cats.

Determine arterial blood pressure range that diplomates of the American College of Veterinary Anesthesia and Analgesia (ACVAA) and European College of Veterinary Anaesthesia and Analgesia (ECVAA) use to define intraoperative hypotension in dogs and identify the threshold values used for intervention. ⋯ There was agreement between ACVAA and ECVAA diplomates on the definition of intraoperative hypotension in dogs during anesthesia. The blood pressures used to define hypotension were similar to the pressures that would prompt diplomates to start treatment. Readers could infer that diplomates define hypotension as a clinical condition that requires treatment at the time of diagnosis.

To evaluate the incidence of myoclonus (involuntary movements during anaesthesia, unrelated to inadequate hypnosis or analgesia, and of sufficient severity to require treatment) in dogs anaesthetized with a TIVA of propofol with or without the use of fentanyl. ⋯ This study shows that 1.2% of dogs, undergoing TIVA with propofol with or without fentanyl administration, developed myoclonus, which required to be, and were treated successfully pharmacologically. The cause of this phenomenon is yet to be determined.
